| 2 | Monetary policy,accounting conservatism and trade credit显示文摘Using a sample of A-share listed firms in China during the 2003–2012 period,this paper investigates the effect of accounting conservatism on trade credit,taking changes in monetary policy into account.We find that corporations with higher accounting conservatism obtain more trade credit and that accounting conservatism has a greater influence on trade credit under tight monetary policy.Furthermore,the backgrounds of the supplier and customer influence the positive relationship between accounting conservatism and trade credit.This influence is more evident when a company is privately owned and has greater market power,and less evident when the supplier or customer is the controlling shareholder. | Bingbin Dai Fan Yang | 2015 | China Journal of Accounting Research2015，，4： | 2 |
| 3 | Complement activation by phospholipids: the interplay of factor H and C1q显示文摘Complement proteins in blood recognize charged particles.The anionic phospholipid(aPL)cardiolipin binds both complement proteins C1q and factor H.C1q is an activator of the complement classical pathway,while factor H is an inhibitor of the alternative pathway.To examine opposing effects of C1q and factor H on complement activation by aPL,we surveyed C1q and factor H binding,and complement activation by aPL,either coated on microtitre plates or in liposomes.Both C1q and factor H bound to all aPL tested,and competed directly with each other for binding.All the aPL activated the complement classical pathway,but negligibly the alternative pathway,consistent with accepted roles of C1q and factor H.However,in this system,factor H,by competing directly with C1q for binding to aPL,acts as a direct regulator of the complement classical pathway.This regulatory mechanism is distinct from its action on the alternative pathway.Regulation of classical pathway activation by factor H was confirmed by measuring C4 activation by aPL in human sera in which the C1q:factor H molar ratio was adjusted over a wide range.Thus factor H,which is regarded as a down-regulator only of the alternative pathway,has a distinct role in downregulating activation of the classical complement pathway by aPL.A factor H homologue,β2-glycoprotein-1,also strongly inhibits C1q binding to cardiolipin.Recombinant globular domains of C1q A,B and C chains bound aPL similarly to native C1q,confirming that C1q binds aPL via its globular heads. | Lee Aun Tan Bingbin Yu Francis CJ Sim Uday Kishore Robert B Sim | 2010 | Protein & Cell2010，1，11： | 2 |

| 8 | Dramatical hydro-sedimentary changes induced by bamboo fences over mangrove tidal flat of the largest delta in Beibu Gulf, southwestern China显示文摘Mangrove forest is one of the most important ecological and environmental resources by effectively promoting tidal flat deposition and preventing the coastal region from typhoon.However,there have been mass loss of mangrove forests due to anthropogenic activities.It is an urgent need to explore an effective way for mangrove restoration.Here,three rows of bamboo fences with hydro-sedimentary observation set over Aegiceras corniculatum mangrove tidal flat of the Nanliu Delta,the largest delta of Beibu Gulf,China,were conducted to analyze the hydro-sedimentary variations induced by bamboo fences.Results identified that the mean horizontal velocity Um per burst(20 min)decreased by as much as 71%and 40%in comparison with those without bamboo fences in March and November,respectively,when the tidal current entering the bamboo area during flood.The maximum of mean horizontal flow velocity Um-max at bamboo area was 50%–75%of that without bamboo fences during ebb tide.The suspended sediment concentration of bamboo area suggested a maximum reduction of 57%relative to bare flat during flood,and was 80%lower than bare flat at ebb peak.Moreover,the turbulent kinetic dissipationεat flood tide was significantly higher than that at ebb tide,while the bamboo fences greatly increased the turbulent kinetic dissipationεby 2 to 5 times relative to bare flat,resulting in an increase of the bed elevation by inhibiting the sediment incipient motion and intercepting suspended sediment.The siltation rate at the bamboo area was 140%and 29.3%higher than that at the bare flat and the region covered with A.corniculatum,respectively.These results highlight that bamboo fences can effectively attenuate tidal current and thus promote siltation over mangrove flat,which contribute great benefit to mangrove survival. | Zuming Huang Zhijun Dai Riming Wang Xiaoyan Zhou Wenhong Pang Jiejun Luo Bingbin Feng Baoqing Hu | 2023 | Acta Oceanologica Sinica2023，42，7： | 0 |
| 9 | Calcification of planktonic foraminifer Neogloboquadrina pachyderma(sinistral) controlled by seawater temperature rather than ocean acidification in the Antarctic Zone of modern Sothern Ocean显示文摘Neogloboquadrina pachyderma(sinistral), the dominant planktonic foraminiferal species in the mid-to-high latitude oceans, represents a major component of local calcium carbonate(CaCO) production. However, the predominant factors,governing the calcification of this species and its potential response to the future marine environmental changes, are poorly understood. The present study utilized an improved cleaning method for the size-normalized weight(SNW) measurement to estimate the SNW of N. pachyderma(sin.) in surface sediments from the Amundsen Sea, the Ross Sea, and the Prydz Bay in the Antarctic Zone of the Southern Ocean. It was found that SNW of N. pachyderma(sin.) is not controlled by deep-water carbonate dissolution post-mortem, and can be therefore, used to reflect the degree of calcification. The comparison between N. pachyderma(sin.) SNW and environmental parameters(temperature, salinity, nutrient concentration, and carbonate system) in the calcification depth revealed that N. pachyderma(sin.) SNWs in the size ranges of 200–250, 250–300, and 300–355 μm are significantly and positively correlated with seawater temperature. Moreover, SNW would increase by ~30% per degree increase in temperature, thereby suggesting that the calcification of N. pachyderma(sin.) in the modern Antarctic Zone of the Southern Ocean is mainly controlled by temperature, rather than by other environmental parameters such as ocean acidification. Importantly, a potential increase in calcification of N. pachyderma(sin.) in the Antarctic Zone to produce CaCOwill release COinto the atmosphere. In turn, the future ocean warming will weaken the ocean carbon sink, thereby generating positive feedback for global warming. | Qianwei SONG Bingbin QIN Zheng TANG Yanguang LIU Zhihua CHEN Jingteng GUO Zhifang XIONG Tiegang LI | 2022 | Science China Earth Sciences2022，65，9： | 0 |
| 10 | Morphotype dependence of Globigerinoides ruber(white)and Trilobatus sacculifer Mg/Ca ratios in the western tropical Pacific:implications for reconstructing the mixed-layer depth显示文摘Planktonic foraminifer Globigerinoides ruber(white)and Trilobatus sacculifer are the most frequently used mixedlayer dwelling species for reconstructing past oceanic environments.Specifically,the Mg/Ca ratios of these two foraminiferal species have been used for reconstructing tropical/subtropical changes in sea surface temperature(SST).However,these two species have different morphotypes,of which the spatial and temporal differences in Mg/Ca ratios and their influencing factors are still unclear.Our objective is to investigate the potential differences between the Mg/Ca ratios of these different morphotypes of G.ruber(white)and T.sacculifer in the western Philippine Sea(WPS)and determine their implications for the reconstruction of SST and upper-ocean structure.Mg/Ca measurements are made on two basic morphotypes of G.ruber(white)[sensu stricto(s.s.)and sensu lato(s.l.)]and T.sacculifer[with(w)and without(w/o)a sac-like final chamber]on samples of Site MD06-3047B from the WPS.Our results reveal that Mg/Ca ratios of different G.ruber morphotypes show consistent differences;and those of T.sacculifer morphotypes show staged variations since MIS 3.It is suggested to select a single morphotype for reconstructing SST changes using the Mg/Ca ratios of G.ruber and T.sacculifer in the WPS.Furthermore,the Mg/Ca ratios between G.ruber s.s.and G.ruber s.l.[Δ(Mg/Ca)_(G.ruber s.s.-s.l.)]downcore MD06-3047B covaries with indexes of summer monsoon.Combining with the core-top results,showing regional variation of differences in theΔ(Mg/Ca)_(G.ruber s.s.-s.l.)over the western tropical Pacific,we propose thatΔ(Mg/Ca)_(G.ruber s.s.-s.l.)may tend to reflect summer mixed layer depth. | Qi Jia Tiegang Li Zhifang Xiong Bingbin Qin | 2023 | Acta Oceanologica Sinica2023，42，11： | 0 |
